3DM-VFTA: A 3D Modeling-Assisted Teleoperation Architecture with Virtual Force-Tactile Feedback under Communication Delay

Guidance, Navigation and Control
Communication delays are common in remote teleoperation tasks, which severely reduce system transparency, force feedback stability, and human operator immersion, thus imposing higher demands on the precision and safety of teleoperation systems.

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Delay-Resilient Voltage Control via Multi-Agent Reinforcement Learning With Causal State Augmentation

IEEE Open Access Journal of Power and Energy
Multi-agent deep reinforcement learning (MADRL) provides a scalable framework for autonomous voltage control through distributed decision-making. However, communication delays can introduce partial observability and degrade coordination among agents ...

From patient advocacy to patient‐driven research: Building active partnerships beginning at the bench to reach the bedside

FEBS Open Bio, EarlyView.
Research is strongest when conducted alongside patients, not just about them. Patient research organizations help integrate patient perspectives into research priorities, study design, and scientific meetings, leading to meaningful patient outcomes and development of relevant therapies.

In fl uence of Communication Delay between the Master and Slave Control Locomotives on Longitudinal Impulse of 20 000 t Heavy-haul Train

机车电传动, 2021
Focus on the communication delay between the master and slave control locomotive, a detailed longitudinal dynamic simulation model considering the communication delay was established based on the multi-body dynamics theory. The influence of communication

Determinants of undergraduate bioscience engagement: Validating attendance barriers and classroom spatial behaviour across institutions

FEBS Open Bio, EarlyView.
Student engagement extends beyond simple attendance. Across 891 bioscience students from three universities, attendance behaviour was associated mainly with structural influences, whereas classroom spatial behaviour reflected affective and sensory factors.

A study on the influence of communication state of wireless coupling system on heavy haul train and its operation

机车电传动, 2023
The communication delay or interruption of the wireless coupling control system would seriously affect the braking and release performance of a train, undermining its operation safety. For the purpose of this paper, the 10,000 t heavy haul formation of 2×

A Secure Hybrid Satellite-Terrestrial Communication Network With AF/DF and Relay Selection

IEEE Access, 2019
This paper makes research on a secure hybrid satellite-terrestrial communication network with eavesdroppers at the primary and secondary receivers. To secure the transmitted messages, we adopt the null space beamforming to the amplified-and-forward (AF ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

On Global Exponential Stability Preservation under Sampling for Globally Lipschitz Delay-Free and Retarded Systems

, 2016
The paper shows that the global exponential stability property is preserved, under suitable fast sampling, whenever the dynamics of the system at hand is described by globally Lipschitz functions.
